Fonts: Noto Sans generated with lv_font_conv (ui-lvgl/fonts/generate.sh,
OFL) replaces ASCII-only Montserrat: European Latin (Latin-1, Extended-A/B),
Greek, Cyrillic + supplement, typographic punctuation, currency, LVGL
symbols + globe; 12/14/16/20 px, clock 40 px digits only (RLE, so
LV_USE_FONT_COMPRESSED is on).
Keyboard (ui-lvgl/Keyboard.h): one layout per script (Latin QWERTY,
Cyrillic, Greek) picked by the same keyboard_main/alt_alphabet prefs as
ui-new, globe key to switch, hold a key for its variants in a popup above
it, one-shot shift, symbols page; compose limit counted in UTF-8 bytes.
First Settings screen (Keyboard: Main / Additional).
Long-press variants and UTF-8 case mapping move to ui-core/KeyboardData.h
and are shared with ui-new, whose Hold-Enter accents gain Romanian,
Turkish, Hungarian, Baltic and Icelandic letters (and ș/ț, Ukrainian /
Serbian letters now capitalise).
Verified on L2 hardware.

New examples/companion_radio/ui-lvgl/ over the shared UI Core (env
Wio_Tracker_L2_companion_solo_lvgl, LVGL 9.2.2, pool in PSRAM):
status bar, home (clock, unread), conversation list (channels + recent
DMs with unread badges), contact picker, conversation view with bubbles,
delivery / relay markers and on-screen keyboard, toasts for Core events,
display auto-off with wake on touch / button. Board glue (LovyanGFX
flush + GT911 touch) isolated in LvglPort.h; design tokens in Theme.h.
UiCore gains the first frontend actions, sendDirectText() and
sendChannelText(), and drives DM auto-resend + unread reconcile from its
own loop (removed from ui-new's loop). MessageHistory exposes newest-first
DM ring iteration and a public contactByPrefix().
Verified on L2 hardware: navigation, send/receive, sleep/wake.
